1

Probability distribution of a random variable

describes all the possible values and likelihoods that a random variable can take within a given range

2

bivariate distributions

relationship between two random variables

3

When to use the binomial distribution (4)

1. fixed # of trials 2. only 2 outcomes 3. prob. of success is the same in each trial 4. trials are independent

4

When to use Poisson distribution (4)

1. probability is the same 2. occurrence of event is independent

5

Poisson distribution if mu is less than 5

mean is very high or probability is very low

6

discrete uniform probability distribution

a probability distribution for which each possible value of the random variable has the same probability

7

expected value

a measure of the central location of a random variable

8

variance

ways to measure the spread - or variability- of a sample or how far aways from the "norm" a result is

9

empirical probability

probability of an event happening is determined by the relative frequency with which a similar event has occurred in the past
